- In general my piling consists of elongated units I of a length corresponding to the vertical dimension or height of walls to be constructed from a plurality thereof and having interlocking elements whereby adjacent units of piling forming jetted or slid into interlocking relation in the usual manner employed in placing ordinary steel sheet piling. My units may, of course, be made in various lengths so as to provide spaces which may be filled as with concrete.

a portion of a wall may be longitudinally driven,

Referring to the drawings and particularly to Figs. 1 and.2, one form of my piling includes an I-beam 1 having flanges Ia. A pair of elongated rectangular plates 8, disposed parallel to the I-beam I and each other, are secured to the 5 flanges la of the I-beam I by suitable means such as the rivets 8a with their longitudinal center lines in the plane of the web of the I-beam 1. Each of the longitudinal free edge portions of the plates 8 is provided with interlocking ele- 10 ments 9 of the type commonly used on interlocking steel sheet piles. All of the respective interlocking elements 9 are disposed with like ends uppermost, so that the interlocking elements 8 on facing edges of respective adjoining pile units 15 of a wall formed thereof are complementary to each other. i

The corner unit shown in the right hand portion of Fig. 1 is constructed in the same manner as the straight wall units shown to the left thereof with the exception that the elongated rectangular plates 8b and 8c are of suitable dissimilar widths and are each bent at right angles along lines parallel to and near to the longitudinal center lines of the plates. Obviously, if a corner of other than 90 degrees is desired, the angle to which the plates 81) and 8c are bent may differ from a right angle in accordance with the desired angle of the corner.

In constructing a wall with my pile units, each successive unit is first placed with the lower ends of one pair of the interlocking elements 9 thereof aligned with the upper ends of the unoccupied pair of interlocking elements 9 of the previously installed pile unit and is then driven downwardly to the same level as the previously installed unit or to the desired level so as to telescope the aligned interlocking elements 9 of the respective pile units into fully engaged relation with each other.

The form of my interlocking pile shown in Fig. 3 consists of an H-beam Ill having interlocking elements II on the free edges of each of its respective flanges. The interlocking elements II on the respective flanges formedon one edge of the web of the H-beam iii are disposed with like ends uppermost and the interlocking elements ii on the respective flanges formed on the other edge of the web have ends disposed upp rmost which are alike but which are opposite to the uppermost ends of the interlocking elements ii on the first mentioned flanges, as shown.

The form of my piling shown in Fig. 4 is similar to the form shown in Fig. 3 except that the inter;

locking elements II on the flanges of its H-beam {uppermost which are opposite to the uppermost ends of the first mentioned elements. With such an arrangement of interlocking elements each pile unit, when driven in forming a wall, is so disposed that the upwardly facing end thereof is the end corresponding to the downwardly facing end of the preceding pile unit.

In Fig. 4 the interior spaces formed in a wall built of myvpiling units are filled with material [4, such as concrete, earth, sawdust, cinders or any other desired material. The material with which the spaces are filled acts -very effectivelyto strengthen the wall and to seal the joints therein. The forms ofv my piling-shown in Figs.

1, 2, and 3 and the forms shown in Figs. 5 and 6 and to be described are. of course, adapted for filling in the same manner. One interior space of the piling shown in Fig. 1 is shown so filled with material Id.

The form of my piling 'shown in Fig. 5 is similar to the form shown in Fig. 4 except that the interlocking elements i3 of diagonally opposite flanges are omitted. The flanges not having interlocking elementsthereon may be of any desired width ranging from the full width shown in Fig. 5 down to a width approaching zero.

The form of my piling unit shown in Fig. 6

is. similar to that of Fig. 1 relative to the arrangement of its interlocking elements I5 and is similar to the forms of Figs. 3 and 4 in that the interlocking elements l5 are carried by an H-beam l4. However, the interlocking elements l5, instead of being formed integrally with the H-beam i6, are formed with mounting flanges I5a which are secured to the marginal free edge portions of the respective flanges of the H-beam M by suitable means such as the rivets l1.

Referring to Fig. '7, the form of piling shown therein is substantially the same as the pile unit shown in Fig. 3 except that two webs 18 are provided in place of the single web I 0 of Fig. 3.

The form of pile unit shown in Fig. 8 is similar to the pile unit of Fig. 7 except that a web-like brace IQ of X-shaped cross section is provided in place of the two webs I 8 of Fig. 7.

The corner unit of Fig. 9 includes a pair of elongated rectangular plates 20 and 2| bent at right angles or any otherdesired angles along lines parallel to their respective longitudinal axes and having an interlocking element 22 formed along each longitudinal free edge thereof. Webs 23 extend from the bend of the narrower plate 2i in line with the respective angularly extending portions thereof to the inner side of the wider plate 20 to meet the same at right angles thereto. The webs 23 are secured along their longitudinal edges to the portions of the plates 20 and 2i abutted thereby.

Fig." 10 illustrates another form of my piling for use at comers in walls. The left-hand unit thereof is the same as the previously described unit shown in Fig. 3. The lower unit thereof is the same as the unit of Fig. 3 except that one flange Illa of the H -beam I0 is somewhat wider than the other flanges and ,is bent outwardly at right angles a short distance inwardly of the interlocking element H thereof as shown. The

remaining unit consists of an elongated rectangular plate 24 bent at right angles along a line parallel to its length and having an interlocking element 25 formed on each longitudinal edge thereof. The space within the comer structure formed by the above described units may be filled with any desired filling material id as indicated in the drawings. If desired, the angular bends referred to above may be made at other angles than right angles.

- Fig. 11 illustrates another form of my pile unit -comprising a pair of elongated rectangular plates 26 secured to each other by suitable means in longitudinal portions thereof intermediate their free edges in slightly spaced parallel relation to each other, the spacing being provided by'suitable spacers 21-. The portions of the respective fplates 26 extending laterally in a common directiori from the longitudinal portions at which the plates are secured to each other diverge outwardly and are provided at their longitudinal edges with longitudinally extending interlocking elements 28. The corner unit shown in the right hand portion of Fig. 11 is the same as the straight wall unit to its left except that each of the elongated rectangular plates 29 and 30 thereof is bent at a right angle on a line extending longitudinally thereof as shown and that the outer plate 29 is of slightly greater width than the inner plate 30. The bends in the plates 29 and 311 may, of course, be made at angles other than i right angles if desired. Also the-spaces within a wall formed of the pile units illustrated in Fig. 11 may be filled with any suitable filling material M if desired.

-In all of theforms of my piling unit the webs thereof provide much greater strength and rigidity in a wall formed of my piling units than can be obtained in a single well formed of ordinary steel sheet piling.

It is apparent that I have invented a novel and. improved type of interlocking, double wall steel piling having great strength and rigidity and providing interior spaces adapted for filling with concrete orother material.

It'will, of course, be understood that various changes may be made in the form, details, arrangement and proportions of the parts, without departing from the scope of my invention, which, generally stated, consists in a device capable of carrying out the objects above set forth and in the novel parts and combinations of parts disclosed and defined in the appended claim.

What is claimed is: g Interlocking double walled metal piling comprising a plurality of interconnected pile sections, each section comprising a pair of long channelvlike members having central webs closely spaced from eachother and each member'having outwardly diverging side webs, said side webs terminating in continuous edge interlocking elements and means securing together the central webs' of the pair in closely spaced parallel relation.
